In this study, to better our understanding of the current state of conservation of Cardisoma guanhumi and its habitats, we evaluated the potential spatio-temporal genomic damage of this species across five estuaries in Brazil. The experiment was performed over two consecutive years, and the sampling was performed in the winter and summer seasons. Two genetic tests — micronucleus test and comet assay — were used to quantify the DNA damage. Unlike in the summers and in the winter of 2013, in the winter of 2012 a significant increase was noted in the frequency of micronucleated cells and genomic damage index. The occurrence of genomic damage coincided with the arrival of the harsh winter of 2012 as the water sourced from the coastal rivers significantly affected the estuarine species under study. Our results confirmed that this species was resilient to the atypical climatic conditions, which facilitated the generation of excessive waste.

在这项研究中，为了更好地了解冠心病的保护现状及其栖息地，我们评估了该物种在巴西五个河口的潜在时空基因组破坏。实验连续两年进行，采样在冬季和夏季进行。两种基因检测-微核检测和彗星检测-用于量化DNA损伤。与2013年夏季和2013年冬季不同，2012年冬季的微核细胞频率和基因组损害指数显着增加。基因组破坏的发生与2012年严冬的到来相吻合，因为来自沿海河流的水对研究中的河口物种有重大影响。我们的结果证实了该物种对非典型气候条件的适应力，这有助于产生过多的废物。
